<@U04S45AHA> I’ve noticed that importing `pyparsing` is super expensive, and we import two copies of it, one from `./.bootstrap/pex/vendor/_vendored/packaging/pyparsing.py` and another from `./.bootstrap/pex/vendor/_vendored/setuptools/pkg_resources/_vendor/pyparsing.py` . I don’t know much about this vendoring, but do you know if there’s a nice way to use one twice, rather than load them both?

(The fact that in order to parse requirements (which we don’t even do), we need to do a bunch of static initialising for a parser of the entire python language… Yeah…)

I think we import it 4-5x. Pip also vendors packaging and setuptools.
